Traditional hardwood sash window with decorative features The Traditional Sliding Sash Window is very popular throughout the British Isles.

Our in-house manufactured hardwood timber sashes can be double or triple glazed and are perfect as replacement windows for conservation areas and listed buildings. Traditional sash windows with modern, high performance timber offer elegant slim lines and original Georgian look. Modern technology ensures that our sash windows will not warp or twist. They provide 21st century standards of insulation and security and require very little maintenance. 

Our sash windows come in wide variety of colours and styles, with decorative horns and accessories to match the existing style of your building, as well as with the Georgian bars in multiple design options. Details can be infinitely variable!

We only need an approximate width and height to give you a quote, so have a rough measure of your space and request a quote with your sizes.
